#15105 Grammar Book 5: Parsing and Punctuation
The word 'parse' comes from the Latin word pars, meaning 'part'. To parse a sentence means to take it apart and identify the parts of speech, pointing out their grammatical relationships to each other.
Punctuation marks are symbols that indicate the structure and organisation of written language, as well as intonation and pauses to be observed when reading aloud. In written English, punctuation is vital to ensure that the meaning of sentences is clear.
